Presentation
• Introduction to the project
• Data and methodology
• Findings:
– Cross-sectional analysis of drinking profiles and
health
– Longitudinal analysis of drinking quantity and
frequency over time
• Policy implications
Research Objectives
• To extend understanding of the diversity of patterns of alcohol
consumption at older ages;
• To identify the socio-demographic dynamics of drinking during later life
and the life events that are associated with changes in drinking
behaviours;
• To explore the relationship between drinking and health conditions in
later life;
• To establish the importance of secondary survey data in supporting policy
initiatives directed towards individual health behaviours;
• To inform health policy initiatives on drinking in later life through
identifying the risks associated with excessive drinking (binge drinking or
drinking more than recommended weekly amounts) and the relationship
between alcohol consumption, health and well-being in later life.

Longitudinal Analysis
• Multilevel level longitudinal analysis using alcohol
variables in waves 0, 4 and 5
• Quantity:
– Growth curve model of log of weekly units of alcohol
consumed
– Restricted to drinkers at all 3 time points (3610 valid cases)
• Frequency
– Ordered logistic regression using frequency of drinking in
last 12 months
– Restricted to respondents at all 3 time points (4740 valid
cases)

Main Findings: Drinking, socio-economic status
and partnership
• Older men tend to drink more and to drink more often than
women.
• Men and women in higher income groups and with higher
levels of education drink more and drink more frequently.
• Both the amount that older people drink and how often they
drink declines over time.
• Men who are not in a partnership drink more compared to
men with a partner, though there is no difference in the
frequency of men’s drinking by partnership status.
• For women loss of a partner is associated with a faster decline
in weekly alcohol consumption and with drinking less often.
Main Findings: Drinking in later life and
health
• Poorer self-rated health is associated with not drinking.
• Among drinkers, there is no evidence that a moderate amount
of alcohol consumption improves health in later life compared
to heavy drinking.
• Over time older people with poor self-rated health and
deteriorating health report a steeper decline in the quantity
and frequency of alcohol consumed (similar finding for
depression).
• Those who stopped drinking at the start of the period of
observation and remained in the study were more likely to
experience an improvement in health compared to drinkers.
Policy Implications
•
•
•
•
•
Rethink causality between health and drinking in later life?
Older people moderate their drinking if their health declines.
But the message that moderate drinking is good for you is not supported by this
analysis. Furthermore for this sample we did not find that excessive drinking
causes a deterioration of health in later life.
Those who stopped drinking were more likely to experience an improvement in
health compared to drinkers so cessation may be recommended for older people
in poor health.
Those at most risk of drinking in excess and drinking most frequently are well
educated and have high wealth. This is a concern particularly as the prosperity of
older people improves then this may lead to more people drinking excessively in
later life. This group of successful older people could be resistant to public health
messages.
